A crystal cave below Y 0. The crystals glow but give off no light.

Translucent voxel crystals on deepslate in a pitch-dark cave. Monsters still spawn next to them.

A torch nearby: the crystal cracks and bursts into a cloud of blinding black smoke.

The same crystal cave seen with Night Vision.

The ritual screen: six shards beam their light into the Umbral Heart.

The heart floats between light columns while glowing glyphs stream into it.

In total darkness only the eye slits and the chest gems glow.

Shadow-Plated Iron, Gloom-Gilded, Void Diamond and Abyssal Netherite in daylight.

Load it with shards to repair tempered gear, in the dark.

Grows new crystals in total darkness below Y 0.

Every item of the mod: crystals, the heart, the altar, the anvil and the shadow gear.
